[en] This paper discusses the ionoptical lattice design of the cooler storage ring COSY-Julich with respect to the experimental demands for high momentum resolution, high angular momentum resolution and high luminosities at the internal target station TP1. Since COSY will operate as a storage ring chromatic aberrations have to be carefully compensated. It is shown that three families of sextupoles are sufficient to correct both chromaticity and dispersion

[en] This paper considers the rate of beam phase space growth and beam losses caused by thin internal targets in light ion storage rings without beam cooling. The analysis of transverse emittance growth and beam losses by small angle Coulomb scattering is recapitulated. The formalism is extended to analyze the effects of transverse and longitudinal emittance growth by energy loss fluctuations. All target effects can be parametrized by two quantities, the mean square values θ2rms and δ2rms of the small angle scattering and relative momentum straggling per target traversal. This paper presents simple expressions for the transverse and longitudinal emittance growth, the beam survival probability and the quantities θ2rms and δ2rms. (orig.)

[en] The cooler synchrotron and storage ring COSY is now under construction at the Kernforschungsanlage Julich (KFA). In this paper the technical design as well as the physics program of COSY is presented. The influence of an internal target to the stored beam behaviour is discussed. From this matching conditions between ionoptical parameters and experimental requirements are deduced

[en] Accelerating a polarized beam in a synchrotron requires the highest possible superperiodicity of the lattice in order to minimize the number of depolarizing intrinsic resonances. However, at the cooler synchrotron COSY the standard lattice to accelerate the beam to maximum momentum has a reduced superperiodicity since the harmful transition energy is shifted upwards during acceleration. This procedure allows internal experiments to take data in the whole acceleration ramp. Unfortunately the reduced superperiodicity excites additional intrinsic resonances. To solve this contrary situation a modified beam optics was found which significantly lowers the strength of these intrinsic resonances. Measurements confirming this theoretical concept are presented
